MaskRay added inline comments.


================
Comment at: lldb/source/Core/Section.cpp:570
+  while (file_addr < end) {
+    SectionSP sect_sp = FindSectionContainingFileAddress(file_addr);
+    if (!sect_sp)
----------------
I am a bit concerned about the potential large time complexity here.FindSectionContainingFileAddress is O(|sections|) and this loop usually executes once but can take a lot of iterations in a pessimistic case. See my comment in D84402.


================
Comment at: lldb/unittests/Core/SectionTest.cpp:43
+    Flags:           [ SHF_ALLOC ]
+    Address:         0x0031
+    Size:            0x000f
----------------
Might be useful leaving a comment that there is a gap.
